Synthesis, Molecular Structure, and Anticancer Activity of Cationic Arene Ruthenium Metallarectangles

Mattsson, Johan ; Govindaswamy, Padavattan ; Renfrew, Anna K. ; Dyson, Paul J. ; Štěpnička, Petr ; Süss-Fink, Georg ; Therrien, Bruno

In: Organometallics, 2009, vol. 28, no. 15, p. 4350–4357

The cytotoxicities of a new series of cationic metallarectangles have been established in the A2780 ovarian cancer cell line. Interestingly, the large rectangles incorporating 1,2-bis(4-pyridyl)ethylene linkers are ca. 5 times more cytotoxic (IC50 ≤ 6 μM) than the 4,4-bipyridine analogues (IC50 ≥ 30 μM), thus suggesting a correlation between cytotoxicity and the size...

Template-Directed Synthesis of Hexanuclear Arene Ruthenium Complexes with Trigonal-Prismatic Architecture Based on 2,4,6-Tris(3-pyridyl)triazine Ligands

Freudenreich, Julien ; Furrer, Julien ; Süss-Fink, Georg ; Therrien, Bruno

In: Organometallics, 2011, vol. 30, no. 5, p. 942–951

Cationic arene ruthenium metalla-prisms of the general formula [Ru6(p-cymene)6(3-tpt)2(OO∩OO)3]6+ (3-tpt = 2,4,6-tris(3-pyridyl)-1,3,5-triazine; OO∩OO = 5,8-dioxido-1,4-naphthoquinonato [1]6+ or 6,11-dioxido-5,12-naphthacenedionato [2]6+) have been obtained from the corresponding...

Highly Efficient NMR Enantiodiscrimination of Chiral Octanuclear Metalla-Boxes in Polar Solvent

Barry, Nicolas P.E. ; Austeri, Martina ; Lacour, Jerôme ; Therrien, Bruno

In: Organometallics, 2009, vol. 28, no. 16, p. 4894–4897

Detection of the molecular chirality of a series of octanuclear metalla-boxes can be readily achieved using the NMR chiral solvating agent Λ-BINPHAT in CD3CN: only 0.05 to 0.10 equiv being necessary for a complete baseline separation of some of the proton signals.
